Which are the four nucleotides in DNA?

Explanation:
DNA is built from four nitrogenous bases: adenine, thymine, cytosine, and guanine. This set is what the question is testing—uracil is used in RNA, not DNA, so it doesn’t belong in the DNA nucleotide set. That’s why thymine appears in the correct answer. The bases pair in a regular pattern (A with T, G with C), which underpins accurate replication and transcription. The other options include uracil or omit thymine, which would describe RNA components rather than DNA’s four bases.
